| Research Abstract |
Obstructive sleep apnea syndrome (OSAS) in children is not rare and is a major health problem. Unfortunately, surgery's success rate is not always high because obstruction sites of the upper airway vary considerably. Morphological findings from computed-tomography (CT) do not always coincide precisely with the functional obstruction sites in the upper airway. Consequently, establishing a method to detect the specific obstruction sites of the whole upper airway is indispensable to successful treatment of OSAS. We examined the obstruction sites in an upper airway model of a OSAS child by fluid-structure interaction (FSI) analysis.
We established a new method combining an airway model with FSI analysis. This method can locate the obstruction sites and simulate the magnitude of air pressure and velocity, evaluating the ventilation condition more precisely than with a morphological evaluation alone.
